Because as Michael Scuse, Undersecretary of USDA’s Farm and Foreign Agricultural Service, explained to the Senate Agriculture Committee yesterday:

“Alimport is the exclusive agent for the Cuban government on buying decisions and negotiating purchases from U.S. firms. Alimport not only negotiates contracts for purchase with U.S. firms, but it arranges for payment, takes control of the imports at the Cuban port, and manages the distribution process within Cuba."

And yet, Cuomo and Co. would also like for the U.S. to extend Castro's Alimport financing.

The second was Infor, a Manhattan software company, that purportedly reached an agreement (in principle) to provide its software to a Castro regime-owned company "so it can resell it."

Infor's Cuban partners are deSoft and Softel, two regime-owned software companies, which are off-springs of Castro's UCI (University of Information Sciences).

The UCI was created by Fidel Castro in 2002 to form the regime's "cyber-warriors." It is located at a "former" Russian espionage and communications interception base. Defectors have described it as “a camouflage of Cuba’s G2.”

Infor better lawyer-up as eligible software exports to Cuba are only permitted under exceptions that "contribute to the ability of the Cuban people to communicate with one another and the United States" or to support "independent economic activity." The reported ends of Infor's deal appear to do neither.

And finally, the Roswell Park Cancer Institute in Buffalo, N.Y., signed an agreement with Castro's Center of Molecular Immunology in Havana to conduct clinical trial for a purported vaccine for lung cancer.

These bio-scams -- courtesy of Castro's regime -- have long been authorized by U.S. law. Here's how they work. And then, they unravel.
